Non-typhoidal Salmonella osteomyelitis in healthy children is a very rare condition. A previously healthy 7-year-old boy presented with foot pain following a small injury. Local inflammatory signs of the foot were observed, with a normal radiograph. Two weeks before, he had had gastroenteritis. Assuming cellulitis, flucloxacillin was began. Early during admission, surgical subcutaneous abscess drainage was performed and Salmonella enteritidis was identified. According to bacterial susceptibility, antibiotherapy was changed to ceftriaxone. A foot radiograph and an MRI scan, performed on the 9th and the 12th days, revealed findings suggestive of osteomyelitis of the metaphysis of the fifth metatarsal. Clinical worsening persisted and surgical extensive debridement was needed. A 6-week antibiotic treatment was completed, with a good outcome. Osteomyelitis with a poor evolution in children with risk factors (prior gastrointestinal illness, warm weather and previous exposure to antibiotics) can raise the possibility of a non-typhoidal Salmonella infection.

Non-typhoidal Salmonella usually manifests as a self-limited acute gastroenteritis but may also cause severe invasive infections almost exclusively among children or immunosuppressed patients. A previously healthy 22-year-old man developed high fever with coma, multiple organ failure and shock. He had visited another hospital complaining of fever 2 days previously and was diagnosed with a common cold. No obvious site of infection was identified by radiology and a rapid test for influenza A virus was positive, indicating possible influenza-associated encephalopathy. However, blood as well as CSF culture yielded Salmonella enterica serotype Enteritidis. Therefore, the patient was considered to be suffering from bacterial meningitis with septic shock concomitant with influenza infection. Antiviral drugs and therapy for septic shock were initiated. He stabilized relatively quickly and his mental status dramatically improved. The patient denied preceding gastrointestinal symptoms, but mentioned that he received positive fecal Salmonella species culture results without medical intervention about 3 months previously. His laboratory values showed marked improvement but his elevated inflammatory markers and fever were sustained. On the 17th day of hospitalization, he complained of back pain and MRI showed lumbar vertebral osteomyelitis. This case indicates that (i) invasive Salmonella infection can be developed even in previously healthy adults; (ii) chronic carriage of Salmonella is a predisposing factor to development of invasive infections, and influenza infection may contribute to such "breakthrough infections"; (iii) attention to manifestation of metastatic extra-intestinal foci even after resolution of sepsis is necessary.

Non-typhoidal Salmonellae are Gram negative bacilli commonly causing self-limiting gastroenteritis, representing a public health issue particularly in tropical countries. Further, the epidemiology of invasive infection by non-typhoidal Salmonella species is poorly understood. Herein, we presented a case of an unusual Salmonella enterica subsp. enterica serovar Altona epidural abscess that cause osteomyelitis and psoas abscess in a 52-year-old Japanese man. To ensure adequate antibiotics penetration into the epidural space, the patient was treated with antibiotics in doses similar to those administered for meningitis. We also reviewed the literature on patients who developed non-typhoidal Salmonella epidural abscesses, and we found 10 other previously reported cases. Salmonella Enteritidis was the pathogen most commonly identified, similar to gastroenteritis. More surveillance of non-typhoidal Salmonella serovars, especially in cases of severe infection, and investigation of antibiotic penetration rate into the epidural space are warranted to decide the best treatment course.

Salmonella infection is an international public health concern. Salmonella organisms are Gram-negative bacilli that belong to the family Enterobacteriaceae, and more than 2500 Salmonella serovars have been described. The most common clinical presentations of Salmonella infection are gastroenteritis, bacteremia, enteric fever, and chronic carrier state. Other rare extraintestinal infections include cellulitis, urinary tract infection, pneumonia, endocarditis, meningitis, brain abscess, and osteomyelitis. Salmonella species resistant to first-line treatment such as ampicillin, chloramphenicol, and trimethoprim-sulfamethoxazole are referred to as multi-drug resistant. In recent years, extensively drug-resistant (XDR) Salmonella have appeared in Pakistan; XDR strains are resistant to multiple antibiotics, including first-line antibiotics, fluoroquinolones, and third-generation cephalosporins. We report two interesting pediatric cases who presented with uncommon Salmonella infection. The first case is a child diagnosed with XDR typhoid fever in a country where the strain is not endemic. The second case is a child who presented with a Salmonella urinary tract infection who is otherwise immunocompetent and has no apparent underlying structural abnormalities of the urinary tract.

Salmonella infection predominantly causes four clinical syndromes: enteric fever, gastroenteritis, bacteremia, and asymptomatic carrier state. Salmonella osteomyelitis is an extremely rare manifestation of salmonella infection except in children with hemoglobinopathies. Salmonella osteomyelitis has been reported to mostly affect the diaphysis of long bones and lumbar spine. Here, we describe a case of salmonella osteomyelitis of the right 6th rib in a 74-year-old woman who presented with breast pain, swelling, high fever and local heat. Her medical history showed myocardial infarction; namely, at the age of 71, the patient had undergone the drug-eluting stent placement in the left anterior descending artery. A computed tomography (CT) scan at the first visit to another hospital showed a mass in the chest that invaded the ribs. 18F-fluorodeoxyglucose-positron emission tomography-computed tomography imaging showed a lesion suspected to be a mammary malignant tumor. A needle biopsy revealed mesenchymal cells and suspected mammary sarcoma. However, the osteomyelitis of the rib was diagnosed when pyogenic tissue was observed during an open biopsy. The bacterial culture examination identified Salmonella enterica. Surgical drainage and antibiotic treatment were performed. Importantly, there was no evidence for any underlying disease that could lead to an immunocompromised status of the patient. To our knowledge, this is the first report of salmonella osteomyelitis of the rib presenting in an older female that required differentiation from a mammary tumor. Clinicians should consider rib osteomyelitis when they find swelling and local heat in the female's breast tissue and detect no cancerous tissue.

Salmonellosis is characterized by gastroenteritis and enteric fever in humans and affects various organs, particularly in endemic regions and in immunocompromised patients. Here, we report on a 45-year-old male patient with multifocal osteomyelitis, pneumonia and colonic ulcers caused by Salmonella typhi infection. The patient was admitted to our outpatient department with dysuria, fever and hip pain and had been treated with prednisolone and methotrexate for pemphigus vulgaris for two months. After Salmonella typhi was isolated in the urine culture, the patient was hospitalized and treated according to the antibiogram. However, despite antibiotherapy, the patient's ongoing complaints suggested an existing resistance problem or a rare or atypical involvement of Salmonella spp. As immunosuppressive agents were not used in high doses or for prolonged periods, this disease course and severity were not expected. For an infectious process with an atypical course or multiorgan involvement, particularly in endemic regions and immunocompromised patients, salmonellosis should be considered in the differential diagnosis.

We present a case of vertebral osteomyelitis in a previously healthy, adolescent Caucasian female athlete. After months of lower back pain, spinal imaging demonstrated phlegmon and suspected osteomyelitis of the L4 vertebral body. A bone biopsy was obtained, and microbiologic cultures yielded pure growth of Salmonella enterica subsp. enterica serovar Poona (S. Poona), a member of the nontyphoid Salmonella group associated with food-borne gastroenteritis in the United States. This case represents the first reported association of S. Poona with osteomyelitis and is interesting in that the infection developed in a patient without traditional risk factors for invasive Salmonella disease (i.e. sickle cell disease). This case highlights the importance of keeping a broad differential diagnosis for lower back pain and emphasizes the value of obtaining specimens for microbiologic culture to aid in diagnosing non-traditional and potentially emerging bacterial pathogens.
